1
Basic specification: Same as MBM29LV400TC (except size and part of sector configuration)
Operation modes:
(1) 64-bit CPU mode:
CPU reads and executes programs in word (32-bit) length units.
Flash writing is not possible.
Actual Flash Memory access is performed in d-word (64-bit) length units.
(2) 32-bit CPU mode:
CPU reads, writes and executes programs in word (32-bit) length units.
Actual Flash Memory access is performed in word (32-bit) length units.
(3) 16-bit CPU mode:
CPU reads and writes in half-word (16-bit) length units.
Program execution from the Flash is not possible.
Actual Flash Memory access is performed in word (16-bit) length units.
(4) Flash memory mode (external access to Flash memory enabled)
Features (through combination of Flash memory macro and FR-CPU interface circuit):
Functions as CPU program/data storage memory.
Enables access to 16/32/64-bit bus width.
Enables read/write/erase by CPU (auto program algorithm*).
Functions equivalent to MBM29LV400TC stand-alone Flash-memory product.
Enables read/write/erase by parallel Flash programmer (auto program algorithm*).
*: Auto program algorithm = Embedded Algorithm TM
